The points (-15, r) and (-3, 16) lie on a line with slope 5/4. Find the missing coordinate r.

Setler79 [48]

Answer:

r = 1

Step-by-step explanation:

we know that :

$Slope=\frac{y_{B}-y_{A}}{x_{B}-x_A}$

Then

$\frac{5}{4} =\frac{16-r}{-3-(-15)}$

Then

$\frac{5}{4} =\frac{16-r}{12}$

Then

5×12 = 4×(16-r)

Then

60 = 64 - 4r

Then

4r = 64 - 60

Then

4r = 4

Then

r = 1

I think is b but not sure<br> It could be c

MaRussiya [10]

Hello!! Actually I got A x = 2, y = 12.

Whenever you plug them in, 2(2) + 3(12) = 40

-2(2) + 2(12) = 20

It worked for me this way, I hope this is the right answer. Have a great day!
